Parts for your 2011 Suzuki Splash-Crank angle sensor

2011 Suzuki Splash crank angle sensor — purpose, service and replacement

Yes — the 2011 Suzuki Splash is fitted with a crank angle sensor (more commonly called a crankshaft position sensor or CKP). Technical sources that cover the Splash’s K10B (1.0L) and K12B (1.2L) engines confirm its use: Suzuki Splash/K-series Engine Control System workshop literature (DTCs P0335/P0336), Suzuki Electronic Parts Catalogue entries for the Splash/Agila B platform, and mainstream data services such as Autodata list the CKP as a core engine management input. These references show the ECU relies on the CKP pulse train to calculate engine speed and crank position for fuel injection and ignition timing.

On the Splash, the crank angle sensor sits low on the engine, reading a toothed reluctor on the crankshaft. Its job is to tell the ECU exactly where the crank is, every moment the engine spins. Without that signal, the car will crank but often won’t fire, or it may run roughly and stall. It works in tandem with the cam sensor to allow sequential injection and precise spark, keeping fuel economy tidy and emissions in check.

Servicing-wise, the CKP isn’t a scheduled replacement item in Australia or New Zealand — it’s “on condition.” During routine servicing, a quick visual once-over under the bonnet goes a long way: check the sensor plug for corrosion or a loose fit, look for oil seepage onto the connector, and make sure the harness isn’t chafed near the crank pulley. Metal debris or grime on the sensor tip can distort the signal, a careful clean with sensor-safe spray can help if contamination is present.

Common symptoms of a failing Splash crank angle sensor include hard starting (especially hot), intermittent stalling, misfire at idle, tachometer drop-outs, and the MIL on with codes such as P0335/P0336. Before replacing, a tech will typically scope the signal, verify power/earth at the connector, and inspect the reluctor ring for damage. If replacement is needed, use a quality OE-equivalent unit, set the correct air gap (where applicable), route the loom exactly as factory, and torque the retaining bolt to the workshop-spec. No coding is usually required, clear fault codes, perform a battery reset if advised, and let the ECU relearn idle during a short road test.

Popular questions

Where is the crank angle sensor on a 2011 Suzuki Splash?
It’s mounted low on the engine block, near the crank pulley/harmonic balancer, reading a toothed wheel on the crankshaft. Access is typically from underneath with the undertray off, on some models it can be reached from the wheel arch with the splash guard removed.

What are the signs the Splash’s crank angle sensor is failing?
Typical clues are extended cranking, hot no-start, random stalling at lights, rough idle, the rev counter dropping out, and an engine light with codes like P0335 or P0336. Because wiring damage can mimic sensor faults, a proper diagnostic check is worthwhile before fitting parts.

Does a new crank angle sensor need programming on a Splash?
Generally, no. The ECU will use the new signal straight away. After installation, clear any stored fault codes and let the engine idle for a few minutes, then take a short drive so the ECU can settle trims. If issues persist, double-check connector fitment, sensor air gap, and harness routing.
